Unlike direct tests of __cplusplus, using this macro also works with
(recent enough, i.e. MSVS 2015.3 or later) MSVC versions, even if
/Zc:__cplusplus is not used.
This simplifies some checks and makes some other ones (notably the check
for C++20 used before wxALLOW_COMBINING_ENUMS macro definition) work
with MSVC versions with C++20 support as intended.
This is easy to do and can be useful when using an atomic initialization
counter.
The only platform where not returning the new value might be more
efficient than returning it is Solaris which is not really relevant any
more and on all the other platforms the functions we were already using
provided this value already (or almost, in case of using gcc builtins,
when we just have to use a different one).
This is intentional and won't be changed, although we could, perhaps,
add a wxGetDST() function or similar to make it easier to take DST into
account as well.
Closes#22399.
There are several ways to do it, and it's not clear which one of them
should be illustrated here, but it should definitely be one that works.
Closes#22389.
Don't take the value of "mask" parameter of wxImageList constructor too
prescriptively, it predates support for alpha in wxWidgets by many years
and was never meant to actually suppress using it.
Instead, do the best thing we can in all cases, i.e. use alpha if it's
specified and supported and use mask otherwise. But only create the mask
from light grey colour if we have nothing else if "mask" is true in
wxImageList constructor, as this is a potentially destructive action
that must not be performed if the user has explicitly decided to set
this parameter to false.
Incidentally fix handling of alpha with comctl32.dll v5 (which is used
in the absence of any manifest) by converting it to a mask in this case:
this is not ideal, but better than just using black background as it
happened before, and restores pre-3.1.5 behaviour.
Also simplify the generic version which just has to create the default
mask if necessary and doesn't have to do anything at all in all the
other cases.
Note that these changes required relaxing some of the existing unit
tests as wxMSW implementation now can add alpha channel to the bitmaps
that didn't have it -- but this is a more useful behaviour, and so it
makes more sense to adapt the tests to it rather than doing a less
useful thing just to conform to the tests.
This commit is best viewed with git --color-moved
--color-moved-ws=ignore-all-spac options.
Closes#22349.
Add information about the recommended way of using wxFrame
as a form, i.e., to not create the input controls as its
direct children but use wxPanel for this instead.
Closes#22395.
Reuse the same code for handling mouse events for both rows and columns
instead of duplicating almost (but not quite) the same code for both of
them.
As part of resolving the inconsistencies between the two versions, add
wxEVT_GRID_ROW_AUTO_SIZE corresponding to the existing event with the
same name for the columns.
Closes#22380.
Make wxDC and wxGraphicsContext DPI aware, i.e. add {From,To}DIP() to
them too and make the values returned from Get{DPI,PPI}() consistent
with wxWindow.
Also improve CMake build: add support for finding Cairo when not using
GTK, fix a warning when creating the inplace-config, and mark some
variables as advanced.
See #22346.
Add wxSharedClientDataContainer class storing ref-counted client data
and use it instead of plain wxClientDataContainer in wxGridCellAttr,
wxGridCellEditor and wxGridCellRenderer classes.
This allows to keep the same client data associated with many grid cells
without having to make many copies of it.
Previously it interpreted its argument as being in DIPs, which was
perhaps more convenient, but inconsistent with most of the other
functions and broke the general rule that FromDIP() should be used with
all hard-coded sizes.
Update the sample to use FromDIP() when calling it now, improve the
documentation and fix a bug in AdjustToolBitmapSize() which resulted in
not increasing the bitmap size when moving toolbar sample using "large"
toolbar size from a standard DPI display to a high DPI one: the old code
considered that the new size was the same as the old one and returned
before comparing it with m_requestedBitmapSize, which resulted in the
bitmaps not changing size at all instead of doubling their size as they
were expected to.
wxRibbonButtonBar::GetItemRect() and wxRibbonToolBar::GetActiveTool()
are helpful for positioning other windows (e.g. popup ones) that should
be aligned to tools and buttons in the ribbon bar.
Closes#22329.
This function existed since a long time but somehow was never
documented.
Also minor improvements to the just added documentation of
wxDC::GetDPIScaleFactor().
Restore the old behaviour of wxLocale, which is supposed to use the
default locale and not the preferred language, which may not be the same
(see #22281).
Also apply the following fixes and improvements to wxUILocale:
- Add new GetSystemLocale() method.
- Change the MSW implementation to use the default locale instead of the
preferred UI language for Windows versions below Windows 10.
- Change the Unix implementation to respect LANGUAGE environment
variable and use it for determining the preferred UI languages.
- Use wxUILocale in wxTranslations to determine the preferred UI
languages.
- Use wxUILocale during initialization of internat sample.
Closes#22281.
Closes#22318.
Make this function virtual in the base class so that it could be
overridden to do the right thing in wxAuiNotebook, instead of just
always returning NULL as before and add a unit test checking that it
works.
Explain that wxBookCtrlBase::m_pages may not be used in the derived
classes, but that in this case they must override all the methods using
it.
Finally, "soft-deprecate" wxAuiNotebook::GetPageIndex(), which is
identical to FindPage() now.
This fixes infinite recursion when handling wxEVT_HELP in wxAuiNotebook
in wxUniv too, see #22309.
Closes#15932.
This function returns wxBitmap by object, not by (const) reference since
wxBitmapBundle-related changes.
Also change signature of the other methods taking wxBitmapBundle instead
of wxBitmap now.
And some other minor improvements.
Closes#22306.
This ctor was previously present only in wxMSW, make it available in all
ports to allow the same code to compile everywhere.
In most of them wxDC argument is simply ignored, but in wxGTK and wxOSX
it is used to assign the appropriate scale factor for the new bitmap.
Enable previously wxMSW-only unit test checking for this.
Previously this ctor was only available in wxMSW and wxOSX, which was
especially strange as the equivalent Create() overload, taking wxDC, was
already available in all ports.
Recognize strings returned by setlocale() when using MSVC under MSW too,
if only because it was possible to construct wxLocale using them in the
previous versions and so doing this avoids breaking the existing code.
Also don't assert in FromTag(), even if the input is incorrect, as it is
potentially user-defined (e.g. can come from environment variables under
Unix).
Closes#22247, #22252.
